Application filed S t b 12, 1899. Serial No. 730,256. No model.)

To all rah/07m it may concern.-

Be it known that I, AARON GRAHAM, a citizen of the UnitedStates,residing at Ch ristiansburg, in the county of Montgomery andState of Virginia, have invented a new and useful Window-Screen, ofwhich the following is a specification. p

The invention relates to improvements in window-screens.

The object of the present invention is to improve the construction ofthat class of flyscreens which are provided with fly-escapes and toprovide a simple, inexpensive, and efficient screen adapted to bereadily applied to the sashes of a window without interfering with theoperation thereof and capable of being readily adjusted to form either aclosed screen or one with an escape for flies.

The invention consists in the construction and novel combination andarrangement of parts hereinafter fully described, illustrated in theaccompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure l is a perspective View of a portion of awindow, showing a screen applied to the upper or outer sash,suc'h sashbeing pulled down to arrange the screen at the bottom of the window.Fig. 2 is a vertical sectional view of the same. Fig. 3 is an enlargeddetail perspeptive View of a portion of the screen. l

Like numerals of reference designate corresponding parts in all thefigures of the drawings.

1 designates a rectangular screen suspended from the bottom of the uppersash 2 of a window and consisting of a rectangular frame 4 and a sheet 5of Wire-netting or other suitable screen materiah The side and bottombars of the frame 4: are provided at their outer faces with recesses forthe reception of the adjacent edges of the screen material, which isclamped therein by strips or cleats 6, and the latter have their outerfaces flush with the outer faces of the side and bottom bars of theframe 4.

The top strip or cleat (i has its upper edge flush with the upper endsof the side bars of the screen-frame, and the upper edge of the nettingis extended above the upper ends of the side bars, as clearlyillustrated in Fig. 2 of the accompanying drawings. The top bar '7 ofthe frame 4 is reduced in thickness to 0&- set it from the projectingupper edge 8 of the netting for the purpose of providing an opening forthe escape offlies. The top cleat 6 is supported between its ends byfastening devices 9, which pass through the said top cleat and havetheir inner ends embedded in the top bar 7 of the frame 4. The innerface of the top cleat 6 is designed to be white in order to light up theopening or escape 10, and this may be accomplished by painting orotherwise coating the inner face of the cleat or by constructing thelatter of white pine or other suitable material. The escape-opening willpermit the flies to pass out at the top of the screen, but should it bedesired to close the space or opening 10 to prevent the entrance ofmosquitos the projecting edge 8 may be bent inward against the outerface of the top bar 7 and the fastening devices 9 will assist insupporting the edge of the screen when bent downward in this manner. Theupper edge 8 may be again bent upward when it is desired to provide afly-escape. The screen is secured to the sash by screws or any othersuitable fastening devices,which are arranged as shown in Fig. 2.

. It will be seen that the screen is simple, in-

expensive, strong, and durable, that it is adapted to be readily appliedto a window, and that an efficient fly-escape is alforded. It will alsobe apparent that the projecting edge of the wire-netting at thefly-escape may be bent downward to close the space between the top barof the frame and the top cleat for excluding mosquitos and otherinsects.

Changes in the form, proportion, size, and the minor details ofconstruction within the scope of the appended claims may be resorted towithout departing from the spirit or sacrh ficing any of the advantagesof this invention.

What is claimed is- 1. A screen comprising a frame consisting of sideand bottom bars recessed at their outer faces, and atop bar reduced inthickness and ofiset from the recesses of the side and bottom bars,asheet of screen material arranged with in the said recesses and havingits upper edge projecting beyond the upper ends of the side bars andarranged parallel with the outer face of the top bar and separatedtherefrom by an intervening space or opening and adapted to be bentinward to cover the said space or opening, and cleats secured within therecesses of the side and bottom bars, fitting face and a top cross-piecereduced and offset from the said recesses, a sheet of screen materialarranged within the recesses of the side bars and lower cross piece andextending above the lower face of the top cross-piece,and the cleatssecured within the recesses of the said side bars and lower cross-pieceand having their outer faces flush with the outer faces of such parts, atop oleat located at a point below the upper cross-bar of the frame andat a point below the upper edge of the screen material, whereby thelatter may be bent inward over the intervening space between it and theupper cross-piece, substantially as and for the purpose described.

In testimony that I claim the foregoingas my own I have hereto affixedmy signature in the presence of two witnesses.

AARON GRAHAM.
